They say a picture is worth a thousand words.  How about a motion picture with audio?  I can see this as being a really useful device for people always looking for pens, or have horrible hand-writing, or worse, can't write (for whatever reason).  So many possible uses, I can't see why this wasn't 're-invented' years ago and brought to market.  Anyway its out now, and you can get Play for $59.99.
